After reading this description, it will become apparent to one of ordinary skill in the art how the invention can be implemented in different and alternative environments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this invention belongs. All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in applications, published applications and other publications that are herein incorporated by reference, the definition set forth in this document prevails over the definition that is incorporated herein by reference.

The present invention relates to the detection of leaks, particularly, but not exclusively, to the detection of water leaks, and the protection of surfaces from water damage due to leaks.

An aspect of some embodiments of the present invention relates to an air freshening device for detecting water leaks and protecting surfaces from water damage due to leaks. The device includes a tray and a liner including an air freshening material, designed for releasing a scented substance into the air, and for increase a release rate of the substance when the material comes into contact with water. The tray is placed upon a surface under a water pipe, and is designed for catching water leaking form the pipe, thereby preventing contact between the water and the surface. The presence of the substance in increased quantity in the air is detected, and indicated a water leak.

According to some embodiments of the present invention, the material includes a water soluble barrier, such as a water soluble polymer, which covers the substance. The water soluble barrier covers the scented substance and limits a rate of release of the substance. Once water comes into contact with the barrier and dissolves the barrier, the substance is released into air at an increased rate. The substance may include a volatile substance, such as naphthalene, or an aerosol which includes one or more essential oils.

According to other embodiments of the present invention, the material 112 is designed to react with water, and the released substance is the product of the chemical reaction. The released substance may be, for example a gas, an aerosol or a volatile substance.

Optionally, the substance includes an odorant and may be detected by a user, for example through the user's sense of smell. Alternatively, the substance is designed to be detected by a detector, which is designed to activate an alarm, once a density larger than a predetermined density of the substance in the air is measured by the detector.

The scented substance is characterized by a pleasant odor designed for covering and/or absorbing malodors. The device is therefore further designed, for preventing the area below the water pipe to smell unpleasantly. This configuration may be particularly, but not exclusively, applicable to closed spaces, such as cabinets.

In a variant, the device includes an item supporting member designed for supporting one or more items. Such a device may be used to cover the bottom of a cabinet located under a sink. The item supporting member is designed for being held by the tray above the liner. The item supporting member is designed to support one or more items, while allowing water from a leak to reach the liner. Exemplary item supporting members include a perforated panel, or a wire grid.

According to some embodiments of the present invention, the tray is designed for allowing easy access to the liner, for removing and/or replacing of the liner, without moving the whole device. Such a design may be useful for a device covering the bottom surface of a cabinet, since removing the liner alone may not require a user to remove one or more items placed on the item supporting member of the device. Optionally, access is granted through an openable and closable gate included in at least one of the walls of the tray. Optionally, the tray is characterized by one low wall, above which a space is provided for easy access of the material.

Another aspect of the present invention relates to a method for freshening air, detecting water leaks, and protecting surfaces from water damage due to leaks.

Referring now to the figures, FIGS. 1 a-1 b are schematic drawings representing a device 100 for detecting leaks and protecting surface from leaks. The device 100 includes a tray upon which a material is placed, the material being configured for releasing a detectable substance upon contact with water, according to some embodiments of the present invention. The substance may be a scented substance, designed for freshening air.

FIG. 1 a shows a perspective view of the device 100. The device 100 includes a tray 102, characterized by a front wall 104, a back wall 106, a left wall 108, and a right wall 110. On the surface of the tray 102, a material 112 is placed. According to some embodiments of the present invention, the material 112 is designed to release a scented substance into air, and for increasing the release rate of the substance when water contacts the material 112. The increased quantity of the substance in the air indicates the present of a water leak near the device 100. Alternatively, the material 112 is designed to release a substance (scented or non-scented) into air, only when water 112 contacts the material. The presence of the substance in the air indicates the present of a water leak near the device 100.

The tray 102 is designed to be placed under a water pipe, and collect water from a leak, thereby preventing water from contacting, and potentially ruining, the surface under the pipe. For example, the tray 102 may designed to be placed on the bottom of a cabinet located under a sink. Optionally the tray 102 is made of a substance which is not ruined by contact with water, such as plastic. In an exemplary embodiment of the present invention, the internal length of the front wall 104 and the back wall 106 is about 28 inches, while the external length of the front wall 104 and back wall 106 is about 29 inches; the internal length of the left wall 108 and of the right wall 110 is about 16 inches, while the external length of the left wall 108 and the right wall 110 is 17 inches; and the depth of the tray 102 is about 1.5 inches.

Optionally, the material 112 includes a water soluble barrier covering a volatile substance. The water soluble barrier is designed to be dissolved upon contact with water. Optionally, the barrier limits the release into air of the substance, and the dissolving of the barrier causes an increase in the release rate of the substance in air. Alternatively, the barrier prevents the release into air of the material, and the dissolving of the barrier causes the volatile substance to be released into air. The water soluble barrier may be, for example, made of one or more water soluble polymers, such as polyvinyl alcohol, methyl cellulose, gelatin, or starch.

According to some embodiments of the present invention, the material 112 includes a chemical designed to react with water and release a product of the reaction as the released substance. The product may be a volatile substance, an aerosol, or a gas. In an exemplary embodiment, the material 112 includes a quantity of sulfur trioxide (SO₃), which reacts with water to provide sulfuric acid (H₂SO₄) aerosol, a substance that may be easily detected by a user's sense of smell, optionally along with other scented substances, such as essential oils. Included in the material 112.

The material 112 may be in many different forms, as will be shown below. In FIGS. 1 a-1 b, the material 112 is contained within a liner. The liner is designed to be removable and replaceable by a user. The material 112 contained in the liner releases the substance into air for a finite period of time, which will be hereafter referred to as the material's lifetime. The device 100 characterized by a removable and replaceable liner may be useful for detecting leaks even after the end of the material's lifetime. As the material's lifetime comes to an end, the device 100 may not be used to freshen air, until the liner is replaced. As the liner is replaced by a user, the user will check the tray for the presence of water, and if water is present, a leak will have been detected, even without a substance release.

Optionally, liners are provided in a variety of scents. A user may choose to replace a first liner characterized by a first scent, with a second liner characterized by a second scent. This may be useful, as the user may have grown accustomed to the first scent, and may no longer detect an intensifying of the first scent, as a consequence of a water leak. As the liners are replaced, the user may be more sensitive to an intensifying of the second scent, due to the water leak, and therefore may more quickly detect the water leak.

Optionally, the liner is flexible. In a variant, the liner is made of a absorbent material, such as a typical absorbent material used in most common paper air fresheners.

According to some embodiments of the present invention, a cabinet is provided, the bottom thereof is covered by a device, like the device 100.

FIG. 1 b shows a view of the device 100 from the point of view of an observer located at a position 114 inside the device 100, and looking in the direction 116, toward the right wall 110.

FIG. 2 is a schematic drawing representing a device 150, including a tray 152, upon which is placed a cartridge 154 containing a liner 156 with an air freshening material, according to some embodiments of the present invention.

The device 150 is similar to the device 100 of FIGS. 1 a-1 c. In the device 150, a flexible liner 156 is contained within a rigid cartridge 154. The rigid cartridge 154 facilitates the handling of the flexible liner 156. The flexible liner 156 may bend or crease while being slid into place, due to a force of friction between the liner 156 and the tray 152. The addition of the rigid cartridge 154 to the liner 156 prevents contact between the liner 156 and the tray, and therefore prevents any bending or creasing of the liner 156 due to friction between the tray 152 and the liner 156.

FIG. 3 is a schematic drawing illustrating a device 200 including a tray 202 upon which a material 204 is sprayed, such that a film of material forms upon the tray 202, according to some embodiments of the present invention.

The device 200 includes a tray 202, and a film of material 204. The tray 202 is similar to the tray 102 of FIGS. 1 a-1 b. The material 204 is applied to the surface of the tray 202, by being sprayed from a container 206 upon the surface of the tray 202. Optionally, the material 204 is a solution which includes plastic microscopic spheres, onto which a water based or alcohol based scented liquid is applied. The solution is sprayed onto the tray 202, and left to dry. As the solution dries, a thin film forms around the spheres, slowing down the evaporation of the scented liquid, and therefore sealing in the scent. Wetting the material 204, dissolves the film around the spheres, and reactivates the scent. An exemplary material having such characteristics is NanoSal, developed by Salvona Technologies, Inc.

According to some embodiments of the present invention, the material 204 is sprayed upon a removable liner. When the effects of the material 204, the liner may be removed, sprayed upon again, and placed again upon the tray 202.

FIG. 4 is a schematic drawing, illustrating a device 300 including a tray 302 upon which a material is placed in the form of granules or pellets, according to some embodiments of the present invention.

The device 300 includes a tray 302, similar to the tray 102 of FIGS. 1 a and 1 b, and pellets or granules 304 of material, having the same properties of the material 112.

FIGS. 5 a-5 b are schematic drawings illustrating a device 400 including a material 402, which includes a substance 404 covered by a water soluble barrier 406, wherein the release of the substance 404 in air activates an alarm 416, according to some embodiments of the present invention.

The device 400 includes a tray 401, which contains a material 402. The tray 401 is similar to the tray 102 of FIGS. 1 a-1 b. The material 402 includes a substance 404, which may for example be a volatile substance or an aerosol, as described above. The substance 404 is covered by a water soluble barrier 406, as described above. The tray 401 is placed under a water pipe 408. The water pipe 408 has a leak, and a water drop 410 is part of the leak.

In FIG. 5 b, the water drop 410 reaches and dissolves the barrier 406, and particles 412 of the substance 404 are released into air.

The particles are optionally, detected by a user through the user's sense of smell. Alternatively, the device 400 further includes a detector 414, which measures and monitors a density of the material 404 in air. The detector 414 is connected to an alarm 416. When the density of the material 404 in the air is higher than a predetermined density, the detector 414 activates the alarm 416, as shown in FIG. 4 b.

The detector 404 may detect the presence of material in the air, through photoelectric, ionization, or air-sampling detection, or a combination thereof as is common is the art. The alarm 416 may produce a light, through LEDs or strobe lights, an audible tone, a spoken voice alert, as is common in the art.

FIGS. 6 a-6 c are schematic drawings illustrating a device 500 including a tray 502, which holds an item supporting member 504, the member 504 being configured for supporting one or more items above the material, according to some embodiments of the present invention.

The device 500 includes a panel 504 having holes, such as the hole 506. The panel 504 is held by the tray 502 and is designed to support one or more items, such as bottles 508 and 510. The holes on the panel allow water from a leak to reach the material 503, and the substance to be released into air.

The addition allows a user to more easily remove and/or replace the material 503. Without the panel, the items would be placed directly on the material 503, forcing the user to remove each item, for removing and/or replacing the material 503. The presence of the panel allows the user to lift the panel and items all at once, in order to reach the material 503.

FIGS. 7 a-7 c are schematic drawings illustrating a device 600, including a tray 602 holding an item supporting member 604, the member 604 being configured for supporting one or more items above the material 603, according to some embodiments of the present invention.

The back wall 806 and the right wall 808 are visible in FIG. 9. The low front wall 804 is designed to prevent water from leaving the tray 802, while allowing a user to access the material 810, without the need to displace the tray 802.

If an item supporting member is present, such as the perforated panel 504 of FIGS. 6 a-6 c, or the wire grid 604 of FIGS. 7 a-7 c, the user may reach the material 810 through the opening between the item supporting member and the high edge of the low wall 804, without lifting or displacing the item supporting member and the items held by the item supporting member.

The device 800, with the addition of an item supporting member, as described above, may be used to cover the bottom of a cabinet, in order to protect the bottom of the cabinet from leaks, to detect leaks, and optionally, to give the cabinet a pleasant smell.

FIG. 10 is a flowchart illustrating a method 900 for freshening air, detecting water leaks, and protecting surface from water damage due to the leaks.

At 902, a tray is placed on a surface located under a water pipe, in order to collect water from a leak in the pipe, and protect the surface from water damage.

At 904, a liner containing a material is provided for being placed upon the tray. The material is designed to release an air freshening substance, and for increasing a rate of the release of the substance when the material comes into contact with water. Optionally, the material includes a water soluble barrier covering the substance, as explained above. Alternatively, the material is a chemical designed to chemically react with water, and a product of the reaction is the released substance, as explained above. The substance may be volatile, an aerosol, or a gas. The liner is designed to be removable and replaceable.

At 905, the air freshening substance is released in air.

At 906, the material contacts water. The tray ensures that water does not touch the surface.

At 908, the substance release rate is increased, as explained above.

At 910, the increased release of the substance is detected. Optionally, the substance is detected by a user through the user's sense of smell. Alternatively, the substance is detected by a detector, as explained above. In a variant, the detector monitors a density of the substance in the air, and activates an alarm, when the density of the substance is over a predetermined density, as explained above.

At 912, the liner is optionally removed and replaced, according to need. The removing and replacing may be performed at the end of the material's lifetime. The removing and replacing is achieved by the accessing by a user of the liner. Optionally, the liner is removed and replaced without a need to move the tray. For example, the material may be accessed through a gate or a low wall, as described below.

According to some embodiments of the present invention, a first liner is replaced by a second liner characterized by substance having a scent different than the scent of the substance included in the first liner. This may be useful, as the user may have grown accustomed to the first scent, and may no longer detect an intensifying of the first scent, as a consequence of a water leak. As the liners are replaced, the user may be more sensitive to an intensifying of the second scent, due to the water leak, and therefore may more quickly detect the water leak.

At 914, as the liner is being removed or replaced, the tray is checked for presence of water. This step allows a user to detect a leak, even after the end of the material's lifetime.
